But the Boeing 777, which was to have landed at 1:15 p.m. (4:15 p.m. ET), encountered severe turbulence over the Atlantic Ocean and landed instead at Montreal's Pierre Elliott Trudeau International Airport, she said.

The injured people -- nine passengers and a crew member -- were taken to an area hospital with injuries that are not life-threatening and will stay in Montreal.

The remaining passengers and crew were to travel to Los Angeles aboard an aircraft that was being sent to Montreal from Chicago, Illinois, McCarthy said. The airline's website estimated their arrival in Los Angeles at 8:02 p.m. (11:02 p.m. ET).

The jet that encountered the turbulence was to be inspected for possible damage, McCarthy said.
